Since the 1940s, Toronto has disguised electrical substations as ordinary houses, complete with windows and front lawns.
Their neighbors could mistake them for family homes, although nobody actually lived inside.
Behind the walls, transformers and switching equipment helped distribute electricity throughout surrounding neighborhoods.
The idea grew during Toronto’s postwar housing boom, when demand for electricity surged.
Between 1945 and 1955, the city’s electricity consumption rose 75 percent.
New substations were necessary, but residents did not always welcome industrial facilities nearby.
So utility designers copied the small bungalows appearing across Toronto’s expanding residential streets.
At 640 Millwood Road, wooden shutters, flower beds, and a brick chimney completed the disguise.
Inside, electrical controls occupied rooms that might otherwise have held furniture and family photographs.
A similar substation stood at 386 Eglinton Avenue East around 1945.
Toronto’s archives record an astonishing consequence of the convincing designs.
Some were so believable that burglars actually broke in, expecting ordinary houses.
